Which is renewable ?

Options

A. Wood
B. Organic remains
C. Biogas
D. All the above

Answer

To determine which options are renewable, let's analyze each one step by step:

1. **Understanding Renewable Resources**: Renewable resources are those that can be replenished naturally over time. They are sustainable and do not run out. Examples include solar energy, wind energy, and biomass.

2. **Evaluating the Options**:
- **Wood**: Wood is derived from trees, which can be replanted and regrown. Therefore, wood is considered a renewable resource.
- **Organic Remains**: Organic remains refer to biomass, which comes from plants and animals. Biomass can be regenerated through natural processes, making it renewable.
- **Biogas**: Biogas is produced from the decomposition of organic matter. The production cycle of biogas is continuous as long as organic materials are available, and it does not contribute to net CO2 emissions. Thus, biogas is also renewable.

3. **Conclusion**: Since all three options (wood, organic remains, and biogas) are renewable resources, the correct answer is "all of the above".

Final Answer: **All of the above** are renewable resources.
